I ing machines and aims to produce a machine for inserting fastenings which will be simple in construction and eflicient and reliable in operation.

The invention will be described, byway of example, as embodied in a machine for building heels, in theoperation of which a heel composed of a plurality of lifts assembled by the machine is introduced into a form comprising members depending therefrom for engagement with'the edges of the lifts to effect such relative movementsof, them as may benecessary properly to C01].- stitute the heel. A fastening or fastenings are then inserted into the heel to secure'the lifts together. The heels sometimes become jammed in the form, or fail otherwise to be accurately located in it. Consequently, the form is preferably removably mounted on the frame of the machine so that the operator may readily ascertain the cause of the difficulty and eiiect'its cure. The formoperates to position the heel, which isinoved' upwardly thereagainst, relatively to the fastening inserting mechanism, and an object of r the invention is to associate the fastening inserting mechanism withthe frame o f'the machine and the work-positioningmeans in such wise as to facilitate the inspectionof the work in the positioning means and the emoval of the positioning means from the machine.

To this end an important feature of the invention resides in the combination with work positioning means constructed to POSL tion a piece of work-disposed below said .ineans, of fastening inserting mechanism comprising means for driving .fastenings and means for delivering fastenings thereto and movable to expose the work positioning means to permit ready inspection of the work orthe removal ofthe workposition- 'FASTENING-INSERTING MAcHINn.

ing means when desired. In the illustrated construction, thethroat through which the fastenings are inserted is mounted, on the machine frame separate from themechalllSHl fordelivering the fastenings throat and driving them into the work but may itselfbe readily detached from the 111achine frame to allow the withdrawal of the" work positioning means therefrom;

Other important features of the invention v pertain to means-for delivering fastenings successively to the throat, meansfoi' supplying fastenings to the delivering means, and novel operating means for the supply- 111g means and the delivering means.

Although the invention will be hereinafter described in its application to a machine for building heels, it is recognized that the invention as a whole and certain features thereof are capable of use in other relations including embodiment in an independent machine for inserting fastenings. Accordingly, the scope of the invention is intended to be limitedonly as required by the claims.

Still other objects and features oftheinvention will appear as the description proceeds and will be pended claims.

. Fig. 8 is a cross-section through the plate and carrier; 1 i Fig. 9' is a detail view of the carrier; Fig. 10 is a view'in front elevation ofthe fastening inserting mechanism of the machine its groove 66 in alinement with the slot 42 of the raceway 44 to a position in alinement with a channel 68 formed in the downwardl extending portion 64 of the raceway 44. X member 70 secured to the raceway 44 by screws or'the like has a'portion 72 adapted to overlie the upper surface of the transferrer and formed with a slot presenting a camsurface 74 forengagement withthehead of the nail carried by the transferrer to discharge the nail positively from the transferrer into the channel 68.

In order to insure the proper delivery of the endmost nail in the racewa into the groove'66 .of the transferrer 63, provide a se 'iarator76 movable in a recess formed in the front surface of the portion64 of the raceway and interposed upon movement of tie transferrer ina direction to aline the groove 66 with the raceway slot42between the endmost nail in the raceway and the remaining nails to dispose the endmost nail properly in said groove. Preferably and in the illustrated. construction, the separator 7 6 is operated by connections with the transferrer 63. As shown, the transferrer is formed at one side of its lower portion with a boss 78 in which is received a plunger 80 normally urgedby a spring 82in the direction. of the separator and depending from the other side of the transferrer is a lug 84 I in which is a pin 86, the construction being such that upon movement of the transferrer 63 to the left, Fig. 2, the plunger is car;- ried into engagement with the separator and moves the separator to a positionintermediate between the endmost fastening and the remaining fastenings. The continued movement of the transferrer. 63 after the separator 7 6 has completedsuch movement, causes the plunger 80 tov yield against the resistance of the spring 82. When the transferrer 63 is moved in the opposite direction to convey the nail in the groove 66 to the channel 68, the pin 86 engages the separator 7 6and withdraws it fron'i the path of the nails thereby permitting them to slide downwardly in the slot of the raceway against the'transferrer.

The nails pass from the channel 68 into a tube 88 by which they are conducted to the devices which deliver them intothe passage of the throat 14. 'Such devices in turn comprise a carrier 90 formed with a recess 92 movable from a nail receiving position in alinement with the tube 88 toa positionin alinement with the passage of the throat}14 to deliver the nail into. the passage of the throat. The carrier 90 is guided in its movements by a plate 93 secured by screws or other appropriate means to a projection 94 on the support 16 and having a portion 95 provided with an inwardly extending shelf 96 which supports the nail in the recess 92 1 of the carrier 90. The shelf 96 extends from the nail receiving position of the recess 92 the recess 92 until it passage of the throat.

to the, throat 14so as eifectually to sustain the nail from the time of its introduction into 7 is delivered into the The transferrer 63 and carrier, 90 are driven by common operating means which,

asshown, comprises a lever 98 fulcrumed at 100. to the transferrer 63 and having a slot 102 which receives a pin 104 extending lat ferrer 63 and to a lug 114 projecting outw wardly from the support 16.

It is essential that thepassage 92 of the carrier 90 be accurately alined with the pass'ageof the throat 14. To this end an abutment 116 is provided on the frame 16 for en gagement with the forward extension 118 of the carrier 90, the abutment 116 being so positioned as to discontinue the endwise movement of the carrier 'at the proper time. In order further to aline the passage 92 of the carrier 90 accurately with the passage of the throat V in a direction. laterally of the movement of the carrier 90, theextension 118 ofthe carrier isformed with oppositely inclined surfaces 120 and 122 adapted to engage correspondingly disposed surfaces of the abutment 116. The operating means for the lever 98 is so constructed as to yield upon engagement of the carrier 90 with the abutment 116. shown, such means comprises a lever 124 having an upstanding portion 126, between which and an upstanding boss on-the sleeved shaft, 106 is interposed a spring 130. The spring 130 is stiff enough to transmit the movement of the lever 124 positively to the carrier 90 until the car rier engages'the abutment 116, after which the continued movement of the lever124. merely compresses the spring. The lever 124 is moved in a direction to shift the carrier from nail receiving to nail delivering position by aplunger 132 acting against a guideway 141 formed integral'ly with a plate 142 secured to the slide 16. The carrier is returned to nail receiving position by a spring 143 connected at one end to the lever 124 and at its other end to the slide 16.

The nails, after being delivered to the throat, are driven into the work by a driver 144 carried by a driver bar 146 slidably mounted in guides 1&8 mounted on the supp rt AS shown, the driver bar 146 is op erated by a link 150 connected in turn to a i-ranlc on the shaft 11.

The support 16 is dovetailed on an upstanding portion'loeotf the frame 2 and has iournaied herein a shaft 156 on which is a pinion 1 meshing with rack teeth 166 on the frame 2. The shaft 156 is designed to be rotated manually to move the support 16 in the dcsired direction, and, to this end, it is provided with a hand wheel 16 As show the hand wheel 162 is loose on the shaft 156, and the hub of the wheel is formed with recesses ada )ted to receive the ends of a pin 16% projecting from diametrically opposite sides of the shaft. Means are prefera v provided for securing the support 16 in s1tion on the frame 2. In the illustraretl construction, such means comprises a nut 166 threaded on the shaft 156 and movable by rotation on the shaft into clamping relation with the adjacent wall of the support 16. The inner end of the hand. wheel 162 is formed to engage the nut 166. Accordingly, the hand wheel 162 may be manipulated. either to move one support 16 on he frame 2 or to secure it in adjusted position on said. frame, the hand wheel being drawn outwardly on the shaft 156 into engagement with the pin 16:1 when it is desired to move the support 16 and being thrust inwardly to engage the nut 166 to lock the support to the frame. In order to limit the forward movement of the support 16 to a point such that the passage 92 of the carrier 90 will be accurately alined with the passage of the throat 1 1, a set screw 168 is threaded into a lug 170 projecting laterally from the support. The set screw 168 acts against the bracket 24 upon which the throat l i is mounted. The shaft 11. partakes oi the movements of the support 16 and is Keyed to its driving pulley 172 which is withheld from endwise movement with the shaft by connections 17% with the bearing 112 6 of the shaft.

it is frequently desirable to inspect the form or the work contained therein. In such'case, the slide 16 may be readily moved rearwardly to expose the form. If it is theniound to be advisable to. remove the form from the frame 2, it is necessary only to lift the arm 20 from the pin 22, and to loosen the blocks 10 by which the form is secured to the frame 2.
